EXHAUSTER OR FEEDER FOR MUSICAL-ORGAN BELLOWS.

SPECIFICATION forming part of Letters Patent No. 568,310, dated September 22, 1896.

Application filed March 7, 1896. Serial No. 582,237. (No model.)

To @ZZ whom, t may concern:

Beit known that LJosErH HERBERT CHASE, of Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Exhausters or Feeders for Musical-Organ Bellows, of which the following is a full, clear, and exact description.

In musical-organ bellows the exhausters or feeders of the bellows are adapted and arranged for the requirements of the full power of the organ, and there has been no means provided by which the operation of the eX- hausters or feeders could be lessened, or re-` duced, or cut out when playing a light organ, so that in all bellows as at present constructed the player has to use substantially the saine exert-ion or power in operating the exhausters or feeders for the light organ as for the full organ, and the object of the present invention is to provide a bellows for a musical organ, more particularly a reed-organ, with exhausters or feeders that will operate for the full eect of the bellows when using a full organ and yet can be shut off or reduced in their operation on the bellows when using a light organ, &c., by which the exertions of the player are much reduced or lessened accordingly; and the inventionconsists in a reed or other musical instrument of the construction and arrangement of the exhausters or feeders of the bellows, so that a portion or portions of the exhausters or feeders can be thrown out of operation or dispensed with at the option of the personv playing the organ, all substantially as hereinafter fully described.A

In the accompanying sheets of drawings is illustrated the present invention as applied to a reed-organ, Figure 1 being a vertical section from front to rear through the bel` lows and exhauster of a reed-organ and showing means for operating the bellows. Fig. 2 is a vertical section on line 2 2, Fig. l; Figs. 3 and fi, detail sections of a bellows, showing this invention applied thereto. Fig. 5 is a detail cross-section on line 5 5, Fig. 2, on a reduced scale.

In the drawings, A represents the framework or case of a reed-organ constructed and arranged as usual for the support of the various parts of the organ, and not needing any particular description herein.

B is the bellows, which in the present instance is the usual exhaust-bellows of such organs. This bellows extends substantially the full width of the case, and is secured by its permanent or center board C to the casing at D, by which it is supported in place. E

is the movable board of the bellows and is of 6o the full width of the bellows and is hinged at F to a part of the case, so as to swing or move back and forth from the center board C. The bellows has communication through the passage G with the wind-chest of the organ in the usual manner.

Hin ged at the lower end onthe outside of the bellows center board C are the exhausterboards of the bellows, consisting in the present instance of four, J, K, L, and M, the two 7o middle ones K L being widerthan the outer two J M, each outer two being connected, respectively, to the one next thereto by plates N,

securedby screws a, so that inthe movev ments of the eXhauster-boards K L the outer connecting one, respectively, will move with it. For operation of these boards a strap P is attached at b to each board K L, respectively, which straps run over separate pulleys Q at the front of the organ-case inside and 8o then down and are connected to the ends d, respectively, of two separate treadles R, side by side, hinged at e, for operation by the feet at the front of the organ, as usual.

The bellows has in its chamber springs S,

secured thereto, and the movable boards to the exhausters have on their outside springs U, which springs are the usual ones for the operation of the bellows.

In the present improvement the eXhaust- 9o ers consist of the two wide ones K L and the narrow or auxiliary ones J M, and in adjusting `the widths of these exhausters the center ones are wide or large enough for the general playing and use of the organ, but when more or a full organ is required the outer or narrow ones are used in conjunction therewith.

Each two eXhauster-boards, being connected together by the plate N, are moved together at all times, but the action or operaroo tion of each outer or auxiliary eXhauster is used or not, as desired. The bellows, with its exhausters, is constructed as usual and needs no particular description herein.

On the onterside of the exhauster-boards of each of the smaller or auxiliary exhausters J M, as shown in Fig. l, is secured by one end, f, a tubular flexible connection T, its other end, 71 being secured to a horizontal board V, which extends across and is secured to each side frame lV, the tubular flexible connection forming a passage or chamber A', which communicates with the exhaustionchamber B' by a passage through the exhauster-board,

D' is a passage through the board V, opening' into the tubularconnection A', and over this passage on the outside of the board V is a valve E', hinged at m thereto.

F is a horizontal wire or rod extending along the front of the board and arranged to rock or turn in lugs fn, one at each end of the board, and extending downward from this rod are two arms G', one at each end, the free end of each being' connected to the free end of its respective valve E.

From one end of the rod F an arm ll extends forward, which is pivoted at 'i' to the lower end of a vertical rod J', which rod at its other end is pivoted at l to one arm K' of ahorizontal lever L', pivoted at u to the frame and extending forward in the key-frame.

M is a lever pivoted at i to the side frame, its lower end in position to bear upon the front arm N' of the lever L', its other end having' a side projecting handle n for opera tion thereof, this lever M being' located, preferably, at one end of the key-frame in convenient position for operation thereof by the person playing the organ.

If the handle-lever is swung backward, its lower end presses the lever-arm N' down, and through the rod J' and crank-arms G the valves E to the tubular connections attached to the exhausters are opened, as shown in dotted lines in Fig. l.

lVhen using the full organ, or a large number of the registers or stops of the organ, so that all or nearly all the sets of reeds are in connection with the keys for the sounding of the same, the bellows is operated by all of the exhausters, full effect of the bellows, but if a light organ is being played, or a small number, or only one or two sets of reeds are being used, which do not require the power of the full bellows, a smaller bellows only being needed, in such case, with an organ having' the present invention applied thereto, the player would swing the lever M backward, which opens, through its connecting-rod, the valves E' to the auxiliary exhausters, allowing air then to freely pass into them through the passages C,' which nullilies their effect upon the bellows, notwithstanding their movements in connection with the other or main exhausters, which correspondingly lessens the exertion ofthe player in operating the bellows, but as soon as the full organ or an increase of the registers or such combination requiring the 56eme sets of reeds is desired, which necessitates more air to supply the reeds or pipes, then the operator swings forward the handle-lever M', which allows the valves E to close by their springs and shuts off the admission of air into the auxiliary exhausters at such place, so that then such exhausters in their movements will act and help to exhaust the bellows for the proper sounding of the instrument.

The valves E can be operated in anysuitable manner. They can also be connected or attached to what is called the full-organ register in such man ner that when playing a light organ or using' a small number of reeds, and therefore with the auxiliary exhausters shut off Afrom operation, if the player desires to use the full organ and the full power of the bellows, in pulling' out the full-organ register for such purpose it would also operate the lever and close the valves to the exhausters, so that the full effect of the bellows would be secured, and when shutting olif the full organ the valves would open and lessen the operation of the bellows.

In lieu of rising the form of passage-way shown in Fig. l it can be varied, and in such case it can be in the form shown in Fig. Il, which is of the ordinary shape of a small bellows K', secured to the exhaustsboard and having on its .movable leaf a the valve E', which is connected to the cranlearm as before for opening of the same, and having a communicating passage L to allow of air passing freely through when the valve is opened.

In Fig. 4 another mode is shown, and in this ease the valve E' is secured directly to the exhausterboard over the passage C into the exhauster-chamber, its vfree end being' connected to the crank-arm for operation as be fore, but the effect of all three forms is the same.

On account of a movement baci; and forth of the exhauster-board it is well to have the device for communicating air to the cx` hausters more or less flexible, and such ilexibility is shown in Figs. l and 3, but in Fig. l the movement at the point where the rodarm is connected to the valve of the exhauster-board is so slight that such flexible connection is not needed, the valve working properly as so arranged.

Although this invention is described in connection with exhaust-bellows, obviously it is applicable to force-bellows as well, the parts being' reversed to correspond therewith; also any suitable means can be used to open the valves to the exhausters.

Having thus described my invention, what I claim is` l. In a bellows for an organ, in combination, two or more exhansters or feeders arranged to operate together as one, and means for throwing one of the exhausters or feeders out of operation.
